The Raspberry Pi is a small, low-cost computer designed to promote an interest in computing and programming – but it doesn’t have to be straight-laced computing. In fact, in this article we’ll be showing you how you can use it to turn a Bigtrak into a robot. That’s educational, right?
The Bigtrak is a toy that takes in a list of straightforward commands (Go forwards, turn left, turn right) and then executes them. To make things more interesting we’re going to remove the existing circuitry and replace it with a Raspberry Pi, using a small motor driver to safely control the motors in the Bigtrak, which we’ll then set up to be controlled via a PlayStation 3 DualShock controller.
Everything required on the software side comes pre- installed on the latest Raspbian OS images, so all we need to translate changes from the controller to the motors is a small Python script that uses the Pygame and RPI.GPIO modules.
Storm Energy has upgraded its “SunSniffer” solar plant monitoring system to a Linux-based platform running on a Raspberry Pi SBC.
Germany-based Storm Energy is the latest of a growing number of companies building commercial products based on the hackable Raspberry Pi single board computer. The company’s SunSniffer system is designed to monitor photovoltaic (PV) solar power installations of all sizes, and the latest version can also control the equipment, says the company. The new SunSniffer version adds a Raspberry Pi SBC along with a custom expansion board and customized Linux OS, which combine to enhance the system’s flexibility and upgradability.
This means that future mobile devices using our 64-bit Tegra K1 chip can offer PC-class performance for standard apps, extended battery life and the best web browsing experience – all while opening new possibilities for gaming, content creation and enterprise apps.
Look forward later this year to some amazing mobile devices based on the 64-bit Tegra K1 from our partners. And for hard-core Android fans, take note that we’re already developing the next version of Android – “L” – on the 64-bit Tegra K1.
Samuel Pitoiset continues making steady, great progress on his Google Summer of Code project as a student developer reverse-engineering and implementing NVIDIA hardware performance counters within the open-source Nouveau driver.
For months now he's had a solid understanding of how NVIDIA's performance counters operate and has been working towards exposing them in a NVPerfKit-like open-source manner and exposing them to OpenGL developers. Samuel's latest update revealed his MP counter work was up to a prototype stage while today he has a new blog post concerning the approaches to exposing the performance counters in Nouveau.
Several new ARM devices will be supported by the in-development Linux 3.17 kernel while some less-than-optimally-supported ARM hardware is also getting stripped from the mainline kernel tree.
Olof Johansson emailed in the large batch of ARM changes today for the Linux 3.17 merge window. Some highlights for the pull request consisting of around 750 patches include.
UniPi is seeking Indiegogo funding for a Raspberry Pi add-on for building automation with analog and digital I/O, changeover relays, and 1-Wire interfaces.
The Raspberry Pi has found its way into many a home automation project, from lighting controls to automatic sprinkler systems, and is often used as a prototype for commercial systems. But is the modest RPi up for managing an entire building? No problem, says Czech startup UniPi, which is offering Indiegogo funding packages of 99 Euros ($133) and 109 Euros ($146) for its UniPi building automation add-on board.
The input subsystem pull request has been submitted for the Linux 3.17 merge window.
Among the items in the input pull sent in by Dmitry Torokhov is a rework of the Wacom driver, which now has been converted to the kernel's HID infrastructure and the USB/Bluetooth support has been unified where as previously Wacom was just treated as a USB driver. This big Wacom driver update was done by Benjamin Tissoires. In the Wacom space, there's also now a driver for serial Wacom devices.
Our brand new sister magazine RasPi is here! Issue #1 is out today, available to download through Apple’s App Store. It’s jam-packed full of amazing content and only costs 69p/99¢.
Each month we’ll be walking you through a big Pi project, showing off some of the best work in the community, sharing your tweets, letters and emails, and of course giving you a whole bunch of tutorials to teach you how to get the most from your Raspberry Pi and make amazing things with it.
Takashi Iwai of SUSE has sent in his set of sound/ALSA changes that are queued up for the Linux 3.17 kernel.
The sound subsystem updates for Linux 3.17 are mostly centered around a ton of ASoC updates, but there's also a few noteworthy changes to the commonly used HD Audio code. In particular, upcoming Intel Braswell hardware has its audio supported by the Linux 3.17 kernel. Going along with Braswell as HD Audio changes are fix-ups for several HD-Audio-using systems including the HP Envy TS, Dell XPS 15, and Gigabyte BXBT-2807, among other platforms.
With the Fedora 21 Alpha freeze looming in the rear view mirror, although the object wasn’t as close as it would appear, I thought it was high time that I gave a brief overview of the state of ARM aarch64 in Fedora. Some might assume the silence means not a lot has been happening but this is extremely far from the truth!
